FFEccLinOrb:
--------------------------------------------------------------------------
Compute the continous A,B matrices for linearized relative motion in an
eccentric reference orbit. Discretizes with a zero-order hold if dT provided.
xDot = a*x + b*u
Since version 7.
--------------------------------------------------------------------------
Form:
[a,b] = FFEccLinOrb( n, nu, e, dT );
--------------------------------------------------------------------------
------
Inputs
------
n (1) Mean orbit rate [rad/s]
nu (1) True anomaly [rad]
e (1) Eccentricity
dT (1) Time-step for discretization (optional)
-------
Outputs
-------
a (6,6) Plant matrix
b (6,3) Input matrix
